Hi,

Is there a way to detect BlackBerry Model in asp.net,

I have made some search on the net but i have not find a solution

I try to use userAgent information , but it seem's that the format change from one version to another,

for exemple for BlackBerry 8900 ,

Request.UserAgent = "BlackBerry8900/5.0.0.681 Profile/MIDP-2.1 Configuration/CLDC-1.1 VendorID/-1"

for BlackBerry Torche :

Request.UserAgent = "Mozilla/5.0 (BlackBerry; U; BlackBerry 9800; en-GB) AppleWebKit/534.1+ (KHTML, like Gecko) Version/6.0.0.141 Mobile Safari/534.1+"

Thank's in advance for your Help

You can just use string.Contains to see if the agent has 'Blackberry' within it

Something like..

C#

string agent = Request.UserAgent;
if (agent.ToLower().Contains("blackberry"))
{
    // whatever
}

This should tell you that the client is using a blackberry device, but nothing more specific than that. Is that what you wanted?

Edit after Comment:

Possibly look into the 51degrees mobile device detection project which uses the WURFL device database

This should allow you to determine device models without having to add lots of string parsing

This is really an issue of the browser running on the BlackBerry. You would need to know what browsers are available for BlackBerrys and research there.

May we all know why you need the exact model description?

I see, that is what I had suspected. Look at Manas answer on this page, it looks promising. Cheers!
